I'm gonna call you today to order a vette servo, the .500 tv boost valve, and the .300 intermediate boost valve. I have the Trans Go Reprogram 2-3 kit that came with no boost valves or a servo. I'm about 80% convinced I'm going full manual. Are there any other parts I should add on for a fast shift? I'm not concerned about harshness in the least. I just want the fastest, firmest shift I can get, obviously without harming the trans.

 

Not at the moment.
